If you’re thinking of creating an e-book and can’t decide whether to give it away for free or charge for your hard work, you now have a third option. Yahoo and Adobe have teamed up to provide contextually relevant ads for PDF documents.
According to CNET, publishers upload their PDFs to Yahoo (we assume via Yahoo! Publisher) and then text ads appear in a panel to the right of the main PDF content. The ads are dynamic, giving them flexibility to change based on the content.
Here’s a screenshot from CNET:
While it wasn’t announced, I suspect Adobe will use this new service to make its current "convert documents to Adobe PDF" online service available for free. It currently charges $9.99 per month for the service, but it might be too tempting to offer the service for free, but on the condition that ads are added to the content. I’m not sure who the market would be for that, but heck, we’re adding ads to everything these days. So if my emails can include Yahoo ads, why can’t my next customer proposal.
